Well maybe you could explain what you want. Preferably without redefining the established terms?

I have not heard of any alternatives in this discussion here. Just the old line of lets tune the VM here and there and hope it lasts a while longer.

Because 4k is a good page size that is bound to the binary format? Frankly there is no point in having my text files in large page sizes. However, when I read a dvd then I may want to transfer 64k chunks or when use my flash drive I may want to transfer 128k chunks. And yes if a scientific application needs to do data dump then it should be able to use very high page sizes (megabytes, gigabytes) to be able to continue its work while the huge dumps runs at full I/O speed ...
